WATER-COOLER FOR REFRIGERATORS.

SPECIFICATION forming part of Letters Patent No. 589,377, dated August31, i897. Application filed March 2, 1896l Serial No. 581,546. (Nomodel.)

To all 'Lu/"tom, t mfzg'/ concern,.-

Be it known that I, FRANK H. TRUMBULL, a resident of Palmyra, in thecounty of Wayne and State ofNew York, have invented certain new anduseful Improvements in Refrigerators; and I do hereby declare therfollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and ro use the same.

The invention relates to apparatus for :refrigerating liquids, and hasfor its object to increase their efficiency and economy; and it consistsin the construction hereinafter del scribed and particularly pointedout.

2o or reservoir,vvhich may be of any desired form` in horizontalsection, and 2 indicates filling between the parallel Walls adapted toprevent the conduction of heat.

3 indicates a removable cover alsoprovided with a non-conducting lling.

3' indicates a door in the side of the refrigerator.

Air-fines are provided in one or more corners of the vessel bypartitions 4, which are 3o shorter than the depth of the interior of therefrigerator and so disposed that air can enter each iiue at the bottomand pass upwardly and out at the upper end of the partition into themain chamber. These partitions extend 3 5 across the corners and areattached to the adjacent walls, thus inclosing dues which owing to theirsituation do not practically or seriously diminish the capaci ty of therefrigerator. They permit comparatively Warm air 4o displaced by thatwhich is colder to ascend without passing up through the main chamber,where are situated the objects to be refrigerated.

1i denotes air-inlets into the lues inolosed by the partitions 4. p

5 denotes a grate, preferably made removable, situated in' the lowerpart of the refrigerator.

If desired, a grate G may also be used to 5o supportice,food, or otherarticles. Said grate G may consist of a pipe-coil connected with a lowercoil, as shown. Ice or other'articles can be placed directly on thepipe-coil, if desired.

7 indicates an inlet-pipe for water or other 55 liquid. This pipecommunicates with a source of supply and may pass up through the bottomWall of the refrigerator and extend above the lower grate and be formedinto a coil 7. The other end of said coil extends out through 6o therefrigerator-Wall and is there provided with a faucet @substantially asillustrated.

As shown in Figs. l and 2, the liquid-supplyin g pipe 7 enters throughthe bottom of the refrigerator and through the drip-receptacle 8, whichmay be so constructed and arranged that the cold drip 4surrounds. thepipe and overiiows said receptacle and flows down the :pipe into otherWater-holders or overflow-receptacles placed about the pipe and provided7o in some cases with absorbent material, the arrangement being suchthat the cold dripwater from` the refrigerator is made to cool theinlet-pipe and iniiowin g liquid before they enter the refrigerator.

9 denotes a faucet for drawing water directly from or from near therefrigeratingn coil, and 10 is a branch or ,cut-off pipe leading moredirectly from the inletfpipe to the same faucet, said faucet having athree- 8o way cock the ports of which are so constructed and arrangedthat it will permit the discharge of comparatively warm Water from theinlet-pipe through said branch pipev or will close or cut off said pipeand permit cold Water 8 5 to be drawn from the coil.

In practice ice may be placed immediately upon the coil in the lowerpart of the refrigerator, which coil can be supported upon the grate orin any suitable manner. 9o

If preferred, ice can be placed on an upper grate and the entire surfaceof the coil used for the support of articles to be refrigerated.

The drip from the ice of refrigerators leaves them at their coldestplane and is usually nearly ice-cold. The described arrangement forutilizing this cold Waste water for cooling the inlet-pipe is aneconomical one, and the efiiciency of this part of the cooliu goperation is much increased by the overflow and abroo sorbent devicesindicated. These devices may be of the simplest form, and it is onlynecessary that the drip shall be held for a suliicient time in contactwith the inlet-pipe, and cloths, Sponges, sand, or other capillarymaterial can be used to advantage.

The precise arrangement of pipes is not essential, providedsubstantially the same objects are secured in practically the same Way.

I am aware that in the application of a pipe to convey liquid through arefrigerator said pipe has been provided with a housingA filled withgravel and arranged to receive the drip from the refrigerator, and I donot claim devices for utilizing' the drip from a refrigerator except ashereinafter particularly pointed out. By my construction the inlet-pipeis provided ivi th overl-10W cups or basins containing capillary matter.The drip-pipe extends below the upper edge of the upper basin to sealthe refrigerator, and the bottom of the basin is provided with fibrousor like capillary matter depending therefrom and surrounding the Water-inlet pipe. By these means not only is the refrigerator sealed, asusual, but the sealing-cup is utilized to hold both Within and withoutcapillary matter, which prolongs the contact of the cold drip with thepipe. Preferably one or more cups are employed below the sealing-cup.The

capillary matter is exposed to the air and favors the evaporation of theldrip, thereby adding to the refrigerating effect.

Having described my invention, what I claim is l. A refrigerator,aWater-pipe passing into the same through its dripoutlet, a sealingeupsurrounding the pipe adjacent the said outlet and filled With capillarymaterial, and having capillary material connected to its eX- terior toconduct the drip along the pipe be loW the said sealing-cup,substantially as described.

2. A refrigerator, a Water-pipe passing into the same through itsdrip-outlet, a sealingcup surrounding the pipe adjacent the said outletand filled with capillary material, and having capillary materialconnected to its exterior to conduct the drip along the pipe below thesaid sealing-cup,and a secon d cup connected to said inlet-pipe andprovided with capillary material, substantially as described.

In testimony whereof I have signed this specification in the presence oftivo subscribing Witnesses.
